Jill/E1110? To all whom it may concern ED STA i FREDERICK P. IBERGH, OF NEW YORK.

Be it known that I, Fnnminicn P. BERGH,

a citizen ofthe United States, and resident of- Yonkers, in the county of Westchester and State'of New York, have invented a new and useful Improvement in Atom zers,

of which the following is a specification. 1

This invention relates to atomizers and.

has for its object the'jprovision' of a device of this character which will be of high efliciency, very free from clogging, which may be used for atomizing either neutralor'acid substances and which may be readily removed or adjusted from the exterior of the chamber in which the precipitated material is deposited, without interrupting the process.

tively carried out.

Another object is provide certain improvements in the construction, form and arrangement of the several parts whereby the above mentioned obJects may be effec- Previous to my difficulty has been experienced in the use of atomizers owing to thetendency of the material to collect at the spray nozzle and eventually clog the same. This clogging v as .has eitherrequired the use of complicated apparatusfo-r cleaning the nozzle or. the in terruption of the processfor a considerable period of time while the operator entered the chamber in which the material is being precipitated and cleaned thenozzle By my invention I not only promote the efliciency: of the spraying arrangement and prevent the likelihood of the stoppage of the nozzle, but I also provide means for conveniently "adjusting or removing the nozzle for rapidly cleaning or changing the nozzle from outside the chamber, and hence obviate any disturbance oi the process.

A practical embodiment of the invention is represented in the accompanying drawingsinwhich,

Figure 1 represents a top plan view of the atomizer, Fig. 2 represents a side view of the same, Fig. 3 a vertical central section thereof, and Fig. 4 an enlarged detailsection of the spraynozzle and'air tip.

The assembly jblock, or me ans for supporting the. air tip and spray nozzle in uxtaposition, is denoted by 1, and t" may be provided with suitable screws 2 for con:

veniently securing itwto the wall 3 015 the chamber (not shown) which receives the" precipitated materlal. 'Ilus assembly block ATOMIFZER Specification ofLetters fatent. Pa,

fl is provided with a horizontally disposed i interiorly screw-threaded recess 4, fitted to receive the exteriorly screw-threaded end.

of a tube 5 connected with a source of com posed with respect to the recess 4,. and adapt ed to receive the exteriorly screwsthreaded rear end of'an air tip 7. The recesses 4 and 6 communicatethrougli a constricted passage 8 in; the block 1, concentric with the said recesses. also has an angularly disposed hole extendmg therethrough and arranged to snugly receive a feed or spray nozzle 9; the rear end of the'said feed or nozzlebeing adapted for submersion in the liquid to be atomized,

which is conventionally represented in. the drawings as contained in the trough 10.

, The feed or nozzle 9is tubularin ,form and invention, considerable its mouth is formed by cutting the tube obliquely to the axis" thereof, as clealily justinent.- The said feed or nozzle may also 8 5 be provided with a suitable guard 12 secured thereto for preventing it from being forced toofar into the chamber, and to insure that the mouth is up. It will be noted that the wall 3 of the chamber is provided with suit able openings for permitting the-air tip 7 and spray nozzle 9 to be'projected into the interior of the said chamber.

By. setting the air tip in ahori'zontal po sition'and the feed or spray nozzle at an acute angle thereto, :I prevent the dribbling of the nozzle which would result in the accumulation of a deposit at themouth thereof, owing to the wiping efiect' which is obtained by thecontact' of the air with the ion zontaLwhile the mouthof the nozzle is in a horizontal p0s1tion..- Furthermore, by having the mouth -g'reaterin 7 area than the cross section of,the main passage in the feed or nozzle 9, and particularly by producingsgthis structure in the'. manner shown,- 10

I almost positively prevent the possibility of unsatisfactory operation owing to dribamass). 23, 1915.

The assembly block 1 7o bling and also obtain an atomized spray"of.-4

a substantially flat and flaring configura- \-tion, which I have *found to be much more eificient than the usual conical configuration 5 of the atomized spray which results from the operation of previous forms of atomizer.

It will be noted, as particularly shown in V Fig. 4:, that this form of nozzle supplies a relatively enlarged and flat basin (so .to speak) of the liquid, and. that the air scoops ous changes may be resorted to the form, construction and arrangement of the several parts of my at omizer without departing from thespirit and' scope of my inven-,

tionand hence I do not limit myself strictly to the form herein shown and described, but

down into this basin as well as around the edges of the mouth, thus insuring that the spray will go oil in a substantially flat fanlike form of uniform composition.

It will be seen that my invention provides for the convenient assembly of the feed or spray nozzle, in order to provide nozzles of diflerent material in atomizing different substances. For example, to provide material which willresist the action of say, sulfuric acid when atomizing that substance and provide a nozzle of some other suitablematerial when atomizing milk.

Y I desire to have it understood that vari What I claim combination with a receiving chamber,

an atomizer provided with a horizontally.

disposed adjustable air tip, and a spray noz: I

zle arranged at an acute angle to said air 'tip and adapted to be adjusted or removed from outside the --'receiving chamber, said spray nozzle having an elongated mouth with its longitudinal axis parallel to the axis of the air tip.

In testimony, that I claim the foregoing as my invention, I have signed my name in v
